Abstract

PURPOSE:To prevent the breakage of constituting components by a method wherein a thyristor is interposed into a key switch circuit in a starting motor for starting an engine to prevent the starting of the starting motor during inertia rotation or rotatio of the engine. CONSTITUTION:A motor 2 has a pair of permanent magnets 1 as the source of field and becomes a generator during the inertia rotation of the motor while the electromotive force thereof becomes the source of base current of a transistor 10 and the transistor 10 is put ON. Accordingly, the circuit of a resistor 11 is not conducted even when a key switch 7 is thrown in and the thyristor 8 is not also turned ON, therefore, a solenoid switch 4 is not operated and the starting motor is not started. When the engine is being rotated, the output of an alternator 18 puts the transistor 10 ON, therefore, the starting motor is not started in the same manner. Thus, the forming components of the starting motor, such as a pinion, a ring gear or the like, may be prevented from breakage.

7-61319), when the key switch is turned on, the excitation coil is energized, the movable piece and fixed contact close, and the armature begins to rotate, and the shift lever pushes out the binion and engages the ring gear of the engine. In most cases, the engine is started. In other words, the engine is started when the key switch is turned on. If the key switch is turned on while the starter is inertial rotation or the engine is already rotating, the impact of the binding between the pinion and ring gear will be excessive, causing damage to the pinion and the ring gear. This had the disadvantage of causing premature wear and damage to the mating ring gear and starter mechanism parts.

and a key switch 7 for controlling the energization of the holding coil 6, a thyristor 8 disposed between the key switch 7 and each of the coils 5 and 6, and one end of the key switch 7 being grounded via a transistor 10 whose emitter is grounded. , consists of a main circuit in which the collector of the transistor 10 and the gate of the thyristor 8 are connected via a resistor 11.

可動片１２が吸引されて接点１３ａと１３ｂを閉じる。When the key switch 7 is turned on, the transistor 10 is in the off state, so the gate 9 of the thyristor 8 is ignited through the circuit of the resistor 11, and the thyristor 8 is brought into conduction. 6 is energized, the movable piece 12 is attracted, and the contacts 13a and 13b are closed.

This causes abnormal impact force to act on parts such as the pinion and ring gear, leading to damage. It is also possible to accidentally turn on the key switch while the engine is running, which can lead to serious damage.

まず、電動機２が惰性回転状態にあるときについて説明

電エネルギーはトランジスタ１０のベース電流源となる
。Since the electric motor 2 uses the above-mentioned permanent magnet 1 as a field source, when the electric motor 2 rotates by inertia, it becomes a generator, and the generated energy becomes a base current source of the transistor 10.

ないことになる。That is, when the electric motor 2 is rotating by inertia, the transistor 10 is on. Therefore, even if the key switch 7 is turned on at this time, the circuit of the resistor 11 cannot be energized, and the thyristor 8 is not ignited, so the electromagnetic switch 4 also does not operate, and as a result, even if the key switch 7 is turned on, the starter does not start. It turns out.

Since the output of turns on the transistor 10,
Similarly to the above, even if the key switch 7 is turned on by mistake, the starter will not start.
